Port channel for esxi host

[jmenken01]

Greetings All,

I'm trying to create a simple port channel for an esxi host and it keeps showing one port as suspended.

Here are the commands I'm running along with the port channel output.

sw1(config)#int range gi2/37, gi8/11
sw1(config-if-range)#switchport
sw1(config-if-range)#channel-group 25 mode on
Creating a port-channel interface Port-channel 25

sw1(config-if-range)#int po25
sw1(config-if)#switchport mode access
sw1(config-if)#switchport access vlan 201
sw1(config-if)#no ip address
sw1(config-if)#no shut
sw1(config-if)#end 

...

25     Po25(SU)         -        Gi2/37(s)      Gi8/11(P)  

Any suggestions would be helpful

Hi

Have you followed the VMWare guide?

Thanks

Thanks for the reply, that article has been my bible for this. I had it working with 2 ports on the same blade but I changed it this morning when I added a new module to the switch to provide better redundancy.

As you've moved one or more interface to a new module, what is the switch type and the module types you're now using? Do each of the interfaces have the same capabilities? You can use show interface gi<mod>/<port> capabilities to find what each interface is capable of and compare the two.

Does the show interface or show interface status err-disabled command output give any more information as to why the interface is suspended?

Assuming you're using auto-negotiation, have both ports negotiated to the same speed and duplex?

You Sir, have helped me greatly. One of the cards is a 6148, the rest are 6748's and from what I'm reading it doesn't look like these two cards jive together.

Thank you!

Hi,

I would certainly avoid using the WS-X6148-GE-TX on any server facing connections, especially if running those severs at Gigabit Ethernet speeds. The 48 front facing ports are divided into six groups of eight ports, with each group having only a 1GE connection to the switch back plane i.e., 8:1 over-subscription.

Thanks Steve, I'm going to replace this 6148 with a 6748 as this is in a datacenter.
